Abstract
Abstract A high-temperature thermal insulation quilt assemblage consisting of an inner quilt and an outer quilt, each cut according to a pattern so as to conform to the shape and wrap around an object having a surface temperature as high as 3000° F. during operation. The inner and outer quilt each include a silicic-impregnated quartz fabric case, multiple blankets of ceramic insulation material, and quartz-fiber thread cross-stitching to reduce quilt thickness. The inner quilt additionally includes a tantalum foil inserted between two blankets of ceramic insulation material, and sewn-on tie straps. The outer quilt additionally includes sewn-on lacing strips for securing outer quilt abutting edges together; the outermost surface is coated with silicone rubber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A thermal insulation quilt assemblage, comprising: a flat inner quilt having an innermost side and an outermost side, said inner quilt disposed to fit over a surface of a hot object in contact with said innermost side; a flat outer quilt having an innermost side and an outermost side, said outer quilt disposed to fit over said inner quilt with said innermost side of said outer quilt in contact with said outermost side of said inner quilt, said outermost side of said outer quilt coated with silicone rubber; an inner-quilt quartz fabric case having bound edges, covering said inner quilt; an outer-quilt quartz fabric case having bound edges, covering said outer quilt; at least two ceramic insulation blankets included within said inner-quilt case; at least two ceramic insulation blankets included within said outer-quilt case; a tantalum foil inserted between two of said blankets included within said inner-quilt case; holding means for holding said inner quilt in place on said hot object; and securing means for securing adjacent outer quilt edges together.
Claim 2
Dependent Claim
171 words
A thermal insulation quilt assemblage, comprising: a flat inner quilt having an innermost side and an outermost side, said inner quilt disposed to fit over a surface of a hot object in contact with said innermost side; a flat outer quilt having an innermost side and an outermost side, said outer quilt disposed to fit over said inner quilt with said innermost side of said outer quilt in contact with said outermost side of said inner quilt, said outermost side of said outer quilt coated with silicone rubber; an inner-quilt quartz fabric case having bound edges, covering said inner quilt; an outer-quilt quartz fabric case having bound edges, covering said outer quilt; at least two ceramic insulation blankets included within said inner-quilt case; at least two ceramic insulation blankets included within said outer-quilt case; a tantalum foil inserted between two of said blankets included within said inner-quilt case; holding means for holding said inner quilt in place on said hot object; and securing means for securing adjacent outer quilt edges together.
Claim 3
Dependent Claim
36 words
A thermal insulation quilt assemblage as recited in claim 1, wherein said securing means includes lacing strips sewn to said outermost side of said outer quilt near said edges, and wire looped between adjacent lacing strips.
Claim 4
Dependent Claim
23 words
A thermal insulation quilt assemblage as recited in claim 1, wherein at least three ceramic insulation blankets are included within said inner-quilt case.
Claim 5
Dependent Claim
36 words
A thermal insulation quilt assemblage as recited in claim 3, wherein said securing means includes lacing strips sewn to said outermost side of said outer quilt near said edges, and wire looped between adjacent lacing strips.
Claim 6
Dependent Claim
25 words
A thermal insulation quilt assemblage as recited in claim 3, wherein said tantalum foil is inserted between two blankets nearest said inner quilt innermost side.
Claim 7
Dependent Claim
36 words
A thermal insulation quilt assemblage as recited in claim 5, wherein said securing means includes lacing strips sewn to said outermost side of said outer quilt near said edges, and wire looped between adjacent lacing strips.
Claim 8
Independent Claim
93 words
A method for insulating hot objects, comprising the steps of: placing a flat inner quilt having an innermost side and an outermost side against a hot object on said innermost side; manipulating said inner quilt to conform to the surface of said hot object; holding said inner quilt in place on the surface of said object; placing a flat outer quilt having an innermost side and an outermost side over said inner quilt; manipulating said outer quilt to conform to the surface of said inner quilt; and securing said outer quilt in place.
Claim 9
Independent Claim
93 words
A method for insulating hot objects, comprising the steps of: placing a flat inner quilt having an innermost side and an outermost side against a hot object on said innermost side; manipulating said inner quilt to conform to the surface of said hot object; holding said inner quilt in place on the surface of said object; placing a flat outer quilt having an innermost side and an outermost side over said inner quilt; manipulating said outer quilt to conform to the surface of said inner quilt; and securing said outer quilt in place.
Claim 10
Dependent Claim
54 words
A method for insulating hot objects as recited in claim 7, wherein said inner quilt and said outer quilt each include a quartz fabric case having bound edges, and including within each case at least two ceramic insulation blankets, said inner quilt case further including a tantalum foil inserted between two of said blankets.
Claim 11
Dependent Claim
69 words
A method for insulating hot objects as recited in claim 7, wherein said outer quilt includes a quartz fabric case having bound edges and including within at least two ceramic insulation blankets, and said inner quilt includes a quartz fabric case having bound edges and including within at least three ceramic insulation blankets and further including a tantalum foil inserted between two blankets nearest said inner quilt innermost side.
